There was a story that circulated recently about Reb Ahron Leib Shteinman. A menahel from a local prestigious cheder whose chinuch was known to be solid and steeped in the traditions of the fathers and grandfathers approached Reb Aharon Leib. It seems that a week or so beforehand, he was walking to his car and saw some OTD boys who approached him and started beating him. Baruch Hashem he was basically ok after some convalescing. He had recognized them, though, as boys that had been to his cheder, and recalled that they weren’t good boys, but not bad boys then either, and had handled them in the way that he was accustomed to, which was with “physical force”. He never thought twice about his approach, until after this incident. His question to Reb Aharon Leib was whether or not he was right in his derech, which WAS the derech of the generations.
Reb Aharon Leib shlita answered him that today the generation is weak. One can not be mechanech today’s children the way that previous generations had been raised, because today’s children can not hold up to it.
Perhaps that is the problem, as you say, the parents are the same. Today’s generation requires a different approach.
